An independent laboratory using American Society for Testing and Materials Standards (ASTM) tests subjected AMSOIL Synthetic 10W-30 Motor Oil (ATM) along with 10 competing conventional and synthetic 10W-30 motor oils to a series of motor oil tests. The competing oils included petroleumbased Castrol GTX, Chevron Supreme, Halvoline, Formula Shell and Penzoil, as well as synthetic blends Trop Artic and
Motorcraft, and full-synthetic Penzoil Platinum, Quaker State Advanced Full Synthetic and Mobil 1 Extended Performance.
Seven tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant's wear protection properties. The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.
The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engine oil's ability to resist heat and oxygen breakdown when contaminated with oxidized/nitrated fuel, water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine. AMSOIL 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum protection and oil changes are reduced, saving time and money.

MAXIMIZES FUEL ECONOMY, REDUCES OIL CONSUMPTION AND EMISSIONS
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL 10W-30 Synthetic Motor Oil resists high temperature volatilization (evaporation) better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
IMPROVES COLD TEMPERATURE STARTS
The Pour Point Test determines the lowest temperature at which a lubricant will flow. The lower a lubricant's pour point, the better protection it provides in low temperature service. Unlike conventional oils that solidify in cold temperatures, AMSOIL 10W-30 Synthetic Motor oil remains fluid down to -58° F. AMSOIL Synthetic Motor Oil helps engines turn over easier and flows quickly to engine parts for critical start-up protection. Engines start faster and wear is greatly reduced for extended engine life.
CONTROLS ACID FORMATION
Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective
SELLING AMSOIL HELPS ENGINES START EASIER
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and
startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.
PROTECTS AGAINST WEAR
The Four-Ball Wear Test evaluates the protection provided by engine oil under conditions of pressure and sliding motion. The size of the scar left as a result of the test determines the amount of wear protection the lubricant provides. The smaller the wear scar, the better the protection. Tests show that AMSOIL 10W-30 Synthetic Motor Oil has better antiwear performance than all other oils tested. With AMSOIL Synthetic Motor Oil, engine life can be extended and major repairs are often reduced.
